研究了在LTE中采用通用两级提前停止算法进行Turbo译码时CRC编码的错误检测性能。建立了在码块和传输块级别上的误块概率和未检测到的误块概率的分析模型。通过仿真验证了较短CRC长度和块大小的模型。分析模型表明，LTE中24位CRC的设置允许采用低复杂度、稳健且可靠的提前停止算法来降低Turbo译码复杂度。
The error detection performance of CRC coding in LTE with general two-level early stopping algorithms for turbo decoding is investigated. Analytical models for the probability of block error and undetected block error at the code block and transport block levels were developed. Simulations were used to verify the model for shorter CRC lengths and block sizes. The analytical models show the setting of 24-bit CRCs in LTE allows low-complexity, robust and reliable early stopping algorithms to reduce turbo decoding complexity.
